The core challenge was building a sampling system that behaves like a lab instrument while living outdoors: freeze–thaw cycles, wind exposure, limited access for repairs, and strict requirements on sampling integrity.
I focused on design choices that would survive real field conditions and still be maintainable: robust mounting, sensible cable/tube routing, serviceable subassemblies, and clear documentation. The comparisons below show “design intent” versus the as-built hardware installed in the container lab and at the site.
